I’ve been looking for an extension that gives flexible control over cookies, and Cookie AutoDelete is a perfect match. I whitelisted the sites where I need to stay logged in (emails, social media), and all the other tracking garbage gets deleted automatically when tabs close. No more clogged browser cache. 5 stars!

Does what it says and also clears out local storage (sometimes websites use in lieu of cookies) for all websites by default. Setting up per-site/domain exceptions is a two-click process. You can turn off the cleanup notifications if they become annoying.

Warning, no longer works. This project is dead!

A good successor is "Auto-Clear Site Data" by byuserforuser

addons.mozilla.org/en-US/firefox/addon/auto-clear-site-data/

Mais um herói para meu esquadrão!!

Does not work......... No blacklist. No setting to delete everything by default unless whitelisted. wtf is this garbage?

Pls robux

When using machines, and or Win OS that are not the very latest Ex: Windows 10 or below (This may incl. Win 11- Which I don't use) and or if the internet cache is insufficient to workload, esp during long sessions, many sites, (ie: social media, streams etc) can become sluggish, or misbehave in various ways depending on the factors mentioned above. CAD has been VERY helpful to Me, when cleaning the cache, fixes certain cookie accumulation that can hinder optimum functionality.
This extension is excellent when: Configured & compatible with the host device, OS vers, browser settings, running apps/ext. and when used properly, for that which it is specifically designed.
NOTE: It is IMPERATIVE to learn and understand ALL the settings, options and to utilize them correctly. Customize them as per your personal needs. Failure to do this could result in a less then ideal or a negative experience of this fine, useful extension.

It seems to me it no longer works.

Unfortunately no longer works. Says it deleted cookies but the cookies are still there, very deceiving. GitHub Issues ignored, project dead.

What a shame, this is a much needed extension.

This addon is no longer auto deleting cookies that aren't whitelisted. And it seems a number of cookie managers are now suffering the same issue, WTF Mozilla can't add this as a standard features to FF is beyond me.

Needs a blacklist mode.

One of the essential plugins for anonymity. This allows you to control cookies. Firefox have some protection built in but this gives you much more control with whitelists etc just 2 clicks away if you need it which makes it a must to those that want some level of anonymity while surfing the net.
